摘要
２，６－二异丙基苯酚（ＤＩＰＰ）与异戊二烯（ＩＰ）反应生成羟基茚满麝香ＤＤＨＩ，用Ｃ－２催化剂，反应最佳条件为：ＩＰ与ＤＩＰＰ物质的量比为１．３０；Ｃ－２催化剂与ＤＩＰＰ的质量比为１．４０；反应温度为９５℃，产品收率高于文献［２］约１０个百分点以上，高于本院自制Ｃ－１催化剂的收率约４个百分点以上。在１０Ｌ玻璃反应釜中重复试验１２批次后，产品收率仍达到８０．９％，平均收率８０．０％。
The main factors affecting the reaction of 2,6 diisopropylphenol with isoprene to form hydroxyindan musk DDHI were discussed.The optimum reaction conditions are isoprene/2,6 diisopropylphenol=1 30(mol/mol); C 2 cat/2,6 diisopropylphenol=1 4(w/w);reaction temperature was 95℃.C 2 catalyst can be used repeatedly for more than 12 times.It has been proved that C 2 catalyst is better than other catalysts.The yield is 10% more than that of USP and is 4% more than that of C 1catalyst previously made by the authors.
